Those who buy a new PC with Office 2010 pre-installed (between the above dates) will also be entitled to access the offer. Unfortunately, those who bought the product before the opening of the window do not qualify.

In order to upgrade, customers must provide proof of purchase and a legitimate product key.

Subscribers to alternative versions of Office will be restricted to upgrading to variants of Office 365. For example, users of Office University 2010 will be subject to an upgrade to Office 365 University.
